Running executables without using rosrun or roslaunch ??

MY QUESTION :

Do ROS topics still properly communicate (subscribe/publish) in the following situation, even though I DID NOT run executables by rosrun/roslaunch?

If not, is there way to run ROS executables without using rosrun/roslaunch?

SITUATION :

By running catkin biuld, executables are created as (~/catkin_ws/devel/lib/PROJECT_NAME/sample_node)

If I try to run the execuatble as follows, it prints seemingly okay results on screen.

./catkin_ws/devel/lib/<PROJECT_NAME>/sample_node

(roscore runs somewhere anyway.)

NECESSITY :

I want to add ROS publish function in my pre-developed code, which cannot be run by rosrun/roslaunch because it contains other pthreads.

I've done it with Python and didn't have any problems.

I've executed the binary files of ROS c++ nodes directly (without using rosrun or roslaunch) without any problems in the past, as long as your environment variables are set correctly this should work without any problems.
